Bug #: 30037
           Summary: BUG: soft lockup in wineserver
           Product: Wine
           Version: 1.4-rc2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wineserver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

I am running Matlab executable files via Wine 1.4-rc2 and the Matlab Compiler
Runtime. I am running Ubuntu 10.10 with Wine via PPA.

Somewhat surprisingly, the Matlab executables work -- and normally they work
very well.  However, occasionally, the system completely hangs (no mouse
movement, have to use the power button to force the machine off).

On my recent attempt I used Ctrl-Alt-F1 to go to the system console, and got an
error like this when the system crashed:

Bug: soft lockup - CPU#0 stuck for 61s! [wineserver:30095]
Process wineserver (pid: 30095, ti=f6a2c000 task=f69f1960 task.ti=f6a2c000)
Stack:
Call Trace:
Code: <hex bytes>

This message repeats every minute or so.  I do not get a prompt back, so
there's no way to interact with the system except to reboot.
